The atmospherewithin such bodies becomes quickly surcharged with obnoxious elements,enumerated heretofore, unless the windows 2 of the body are 0 ened.Obviously in cold weather such expe iencies are accompanied withdiscom-. fort. Again dust accumulates within the interior of a closedbody, quickly on an extended trip. While not of themselves seri- .ousdefects modern standards and taste demand comfort to the extreme limitin automobile body ventilation and temperature.

Now, I have discovered that by utilizing the cylinder suction' of theengine 3 in the engine compartments of the car I can positivelyreplenish" the air within the closed body-or assenger compartmentwithout subjecting t e occupants thereof to cold, dust or odoriferousobjections. To the carburetor 4. I aflix a length of piping 5 andextend.

the piping into the closed body. The piping 5 is attached as at 6 to theusual carburetor air intake. The piping may be made of metal, or rubberor any material suitable for. the

purpose.

As shown in Fig. 1, the pi ing'5 extends along the interior of the b0 ywall 11 and may be tapped by an auxiliary iping 12 leading into thebottom of the seat It will thus be noted that air sucked'into theconduit 12'must first ass thru the seat cushion 13 thus filtering theair.- It is to be understood that this auxiliary iping may lead into anyi of the seats within t e closed body. Of course auxiliary conduits 5may even lead into a seat, beneath the cushion, exposed to the airconstantly. The main purpose in such case being to eliminate the foreignbodies from the air, sucked into the conduit 12, then drawn through thepiping 5 and finally educed into the carburetor 3. And the auxiliaryconduits may even lead into the passenger compartj ment or dashboardexposedto the air constantl p In Fig. 3, it is observed that the piping5 leads into the spaces 9 between the rafters 15 of the roof frame. Ahollow hub 8 disposed within one of the spaces-9 is affixed to -thepiping 5 and has afiixed thereto along its pe-.

riphery tubular arms 10 that radiate therefrom and feed into each roofspace 9. Here again the hub 8 and, arms 10 may be made of any well knownmaterial, such as metal or rubber, suitable for the purpose. It isobvious that air withdrawn from the body interior 16 into the tubulararms must first pass through the fabric 14 which serves as the ceilingof the interior of the car.

It will be obvious that when the car is being driven at a fairly'highrate of speed on a cold day, that due to the enormous quantity of airconsumed by the carburetor, that there will be a rapid change of air inthe passenger compartment. Even if the windows are shut and the doorsclosed, the suction through the conduit 5 will be so great as to educecold air through door cracks and thus cause the passenger com artment tobecome cold in ashort time. T e greater the speed of the car, thegreater would be this influx of cold air.

Now, I have provided against this rapid influx of air intothe passenger"compartment while driving on a cold da by tapping the main conduit 5with a T ebow 17 as shown in Fig. 6. A short pipe 18 is aflixed to theelbow and houses therein a butterfly valve 19. Levers 21 and 20 areattached in any wellknown mechanical manner to the valve 19 and the handlever 22, so that the valve 19 may be-remotely controlle I by motion ofthe lever 22. Of course the leve 22 may be attached at any point on thedash oard convenient to the autoist. I am not limited in the location ofthe valve, nor in the design thereof. It may be arranged at any pointalong the conduit 5 in the engine complartment.

The operation of t e invention is apparent. The cylinder suction of theengine in the engine compartment automatically withdraws the airsurrounding the outlets of the piping. Before the air reaches thecarburetor intake 6 it is thoroughly filtered and freed from dust andthe hke objectionable substances. Fresh air is constantly supplied fromthe exterior of the car without opening the windows widel A mere crackis sufiicient. The atmosp ere within the closed car has no chance inthis way to become foul, humid or dusty. And simultaneously with thisventilating action, the exhausted air is filtered, by the body itself,and fed to the carburetor in a warmed or semi-warmed state thus greatlyimproving vaporization of the gasoline. Of particular im ortance is thefact that no drafts are create the intake and withdrawal of air relativeto the body being responsive only to a positive and constant cylindersuction.

As pointed out above, while driving on a cold day, the lever 22 would beadjusted so as to open the valve 19 so that a part of the air drawn intothe carburetor would be educed remainder would bedrawn from thepassenger V compartment. The arrows in Fig. 6, show the flow of air insuch-a case. Thus by varying the valve 19, a simple and extremely handymeans is provided to lessen the air demand on the passenger compartmenton a cold day as the car speeds are increased and. the carburetorrequires more air. 1

, Of course, I am not limited to the use of the roof fabric and seatcushions as filtering.

material. It is within the scope of my inaddition to the filteringaction.

It will thus be apparent that I have not only secured a novel system ofventilating the passenger compartment of an automobile by withdrawingair therefrom into the engine compartment, but I have devised means toutilize such withdrawn air in carburetion, and in addition provided acontrol for such withdrawal which is readily accommodated to variationin speed of the car and tempera: ture of the atmosphere,

As many apparently widely different em-. bodiments of this invention maybe made without de arting from the spirit thereof, it will be unerstood, that I do not intend to limit m self to the specific embodimentherein set fhrth except as indicated in the appended claims. a

Having thus described my invention what I claim and desire to protect byLetters Pat'-v ent is:-
